Description

  The present invention relates to a skin pack package in which an object to be packaged is held between a skin pack film and a mount.

The skin pack package is a mount having a design printing layer on the surface of a base material such as cardboard, a package placed on the surface of the mount, and a skin pack that covers the package And a film (Patent Document 1). The skin pack film is adhered to the mount through an adhesive provided on the surface of the mount (the surface of the design print layer), and the packaged item is held between the skin pack film and the mount.
If a skin pack film is used, an article to be packaged can be packaged in a compact and inexpensive manner.

In the skin pack package, the packaged product can be taken out by rolling the skin pack film from the mount.
However, in the conventional skin pack package, since the skin pack film is firmly adhered to the mount, when the skin pack film is rolled up, the base material of the mount causes material destruction, and the base material is a surface layer and a back layer. As a result, the design print layer and the surface layer of the substrate are peeled off together with the skin pack film.
When the surface layer of the base material is peeled off by the skin pack film, the object to be packaged is sandwiched between the surface layer of the base material and the skin pack film. I can't take things out.
Furthermore, when the surface layer of the base material is peeled off by the skin pack film, the design printed layer does not remain on the mount, and the package is taken out even if the handling instruction of the package is displayed on the design printed layer as a design. It will be difficult to read it later.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings as appropriate.
The “surface” of a certain member or layer refers to a surface on the front side (side closer to the viewer) when the skin pack package is viewed from the front (the side directly viewing the skin pack film) shown in FIG. The “back surface” refers to the opposite surface. Furthermore, “upper, lower, left, and right” are used as terms indicating directionality, and these refer to directions when the skin pack package is viewed from the front shown in FIG. 1 for convenience. In addition, the description “PPP to QQQ” means “PPP or more and QQQ or less”.
It should be noted that the specific dimensions and scale ratios of each figure are different from the actual ones.

The skin pack package of the present invention includes a mount, a package, and a skin pack film that holds the package in cooperation with the mount.
The mount has at least a base material, a release layer containing a release agent, and an adhesive layer containing an adhesive in this order. The mount includes, for example, the base material, the release layer, and the adhesive layer in order from the back surface side to the front surface side. On the condition that the mount has the base material, the release layer and the adhesive layer, the other optional layer is one layer selected from the base material, the release layer and the adhesive layer or two selected from them It may be provided between the layers.
Preferably, the base material has a resin coat layer containing a synthetic resin, and the surface of the resin coat layer constitutes the surface of the base material. The mount further includes a design print layer containing a colorant between the base material and the release layer. Such a design print layer is provided on the surface of the substrate (or the surface when a resin coat layer is provided), and the release layer is provided on the surface of the design print layer. The skin pack film is bonded to a base material (mounting paper surface) through an adhesive layer formed of an adhesive.
In the present invention, the release layer containing the release agent has a skin pack film and a substrate either at the interface between the release layer and the adhesive layer or inside the release layer when the skin pack film is rolled up due to the presence of this layer. It is a layer which peels. The resin coating layer is a layer that improves printing characteristics with printing ink. A paper base material provided with such a resin coat layer is generally referred to as a coated paper, while a paper base material not provided with the coat layer is generally referred to as a non-coated paper. The design print layer is a layer on which a desired design is displayed, and is formed from a printing ink containing a colorant and no release agent.

The adhesive strength of the adhesive layer to the release layer is, for example, 1.0 N / 15 mm to 10 N / 1.9 mm, and the adhesive strength of the adhesive layer to the back surface of the skin pack film exceeds 2.0 N / 15 mm, preferably It is 2.5 N / 15 mm or more. If the adhesive strength of the adhesive layer to the release layer is too small, the skin pack film may be inadvertently peeled off in the skin pack package, and the packaged product may fall off. On the other hand, if the adhesive strength of the adhesive layer with respect to the release layer is too high, the skin pack package may not peel at the interface between the adhesive layer and the release layer when the skin pack film is rolled up.
The adhesive strength of the release layer to the surface of the substrate is greater than the adhesive strength of the adhesive layer to the release layer, for example, exceeds 2.0 N / 15 mm, preferably 2.5 N / 15 mm or more.
Each said adhesive strength says the value measured by the method according to 180 degree peeling of JISZ0237. Specifically, the adhesive strength is determined by cutting a laminate having a skin pack film bonded to a mount to be measured into 100 mm × 15 mm, a temperature of 23 ± 2 ° C., a humidity of 50 ± 5% RH, and a speed of 200 mm / min. The maximum strength when peeled 180 degrees.
The said adhesive strength can be suitably set by selection of the material of a base material, a design printing layer, a peeling layer, an adhesive layer, and a skin pack film, the formation pattern and density | concentration of a peeling layer, and an adhesive layer.
Hereinafter, the skin pack package of the present invention will be specifically described.

[First Embodiment]
1 to 4, the mount 2 has a base material 5 and a release layer 6 including a release agent provided on the surface side of the base material 5. Preferably, the mount 2 has a base material 5, a design print layer 7 provided on the surface of the base material 5, and a release layer 6 containing a release agent provided on the surface of the design print layer 7.
An adhesive layer 8 made of an adhesive is provided on the surface of the release layer 6.
The front view shape of the mount 2 is a substantially rectangular shape. However, the mount 2 may be formed in a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, a substantially trapezoidal shape, or the like when viewed from the front (not shown).
The material for forming the substrate 5 is not particularly limited, and is a non-coated paper such as cardboard or plain paper, a coated paper, a synthetic paper similar to the coated paper, a single-layer sheet such as a synthetic resin sheet, a foamed resin sheet, and two or more of these. Various sheet materials such as a laminated sheet in which these sheets are laminated and bonded can be used. The sheet includes what is generally called a film.

The coated paper is an example of a substrate having a resin coating layer, in which a resin coating layer is provided on the surface of paper such as cardboard or plain paper in order to improve printing characteristics with printing ink.
The material of the synthetic paper, the synthetic resin sheet, and the foamed resin sheet is not particularly limited, and examples thereof include polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate, and polyamides such as nylon.
When cardboard is used as the substrate 5, the thickness is not particularly limited, but is, for example, 0.5 mm to 1 mm. Further, if the non-coated paper or coated paper such as plain paper is used as the substrate 5, the basis weight is not particularly limited, for ^example, a ^{50g / m 2 ~600g / m 2} , preferably, 270 g / m ^{2 to} 600 g / m ² . When a synthetic paper, a synthetic resin sheet, or a synthetic resin sheet is used as the substrate 5, the thickness is not particularly limited, but is, for example, about 40 μm to 200 μm.

The skin pack package 1 covers the surface of the mount 2 with a softened skin pack film 4 and then sucks the air between the surface of the mount 2 and the skin pack film 4 toward the back of the mount 2. It is manufactured by adhering the film 4 to the surface of the mount 2. For this reason, as the base material 5 of the mount 2, a material having air permeability in the thickness direction is used.
The non-coated paper such as cardboard and plain paper and the foamed resin sheet in which air bubbles are continuous are the base material 5 having sufficient air permeability in the thickness direction so that air can be sucked smoothly when the skin pack package 1 is manufactured. . The synthetic paper, the synthetic resin sheet, the foamed resin sheet having discontinuous air bubbles, and the laminated sheet including these are base materials 5 having no air permeability in the thickness direction. The coated paper and the laminated sheet including the coated paper are generally the base material 5 having insufficient air permeability in the thickness direction, although there are differences depending on the thickness and material of the resin coating layer. Hereinafter, a base material having sufficient air permeability such as the cardboard is referred to as a “breathable base material”, a base material having no air permeability such as the synthetic paper, and a base material having insufficient air permeability such as the coated paper. These are collectively referred to as “non-breathable substrate”, and both are collectively referred to as “substrate 5”.

When a non-breathable base material is used, air cannot be sufficiently sucked from the back surface side of the base material when the skin pack package 1 is manufactured. Therefore, it is preferable to form air holes in the surface of the base material. (The vent is not shown).
The vent hole is a hole penetrating in the thickness direction of the non-breathable substrate, and examples thereof include a perforation line. The perforation line consists of a plurality of through holes that are intermittently arranged like the sewing marks of the sewing needle. The perforation line can be visually recognized by the naked eye, but instead of or in combination with the perforation line, a plurality of fine holes that cannot be visually recognized by the naked eye are formed regularly or irregularly in the surface of the non-breathable substrate 5. May be.
In addition, although it is not necessary to form the above vent holes in the air-permeable base material, the air holes may be formed in the air-permeable base material.

The design print layer 7 is a layer on which a desired design such as a product name and a product description is displayed using a printing ink containing a colorant. The printing ink is a conventionally known ink, but one that does not contain a release agent is used.
The design printing layer 7 can be formed by applying printing ink to the surface of the substrate 5 by a conventionally known printing method. In addition, the design printing layer 7 may be provided also on the back surface of the base material 5 (not shown). Further, in the present invention, the design printing layer 7 is not limited to the case where the design printing layer 7 is provided on the surface of the base material 5, and the design printing layer 7 may be provided only on the back surface of the base material 5, or The design print layer 7 may not be provided on the substrate 5 (not shown).
Although the thickness of the design printing layer 7 is not specifically limited, For example, it is 0.5 micrometer-5 micrometers. Since the design printing layer 7 is very thin, the air permeability of the base material 5 is not substantially hindered.

The release layer 6 is a resin composition containing a release agent on the surface of the design print layer 7 (the surface of the base material 5 when the design print layer 7 is not provided) (hereinafter sometimes referred to as release layer forming material). Can be formed by applying and solidifying.
The release layer 6 may be provided in a solid shape on the surface of the design printing layer 7 or may be provided intermittently on the surface of the design printing layer 7. The solid shape means a state in which the release layer forming material is applied so as to cover the entire surface of the design printing layer 7 and the application portion 61 of the release layer forming material is continuous in the surface direction of the mount 2. The intermittent means that the release layer forming material is applied to the surface of the design printing layer 7 with some gaps, and the application portion 61 of the release layer forming material is discontinuous in the surface direction of the mount 2.
In the illustrated example, the release layer 6 is intermittently formed in the surface direction of the mount 2 by intermittently applying and solidifying the release layer forming material on the surface of the design print layer 7. The intermittent release layer 6 is composed of a set of application portions 61 of a plurality of release layer forming materials.
The formation pattern of the intermittent release layer 6 (the pattern of the application portion 61 of the release layer forming material when viewed in a plan view) is not particularly limited. For example, in the plan view, a dot shape, a lattice shape, and a stripe shape are used. The shape may be mentioned, and a dot shape or a lattice shape is preferable. Since it can form easily by the printing method, it is preferable that the formation pattern of the peeling layer 6 is a dot form as shown in FIG. The formation pattern of the intermittent release layer 6 may be regular or irregular. The planar shape of the application portion 61 of the release layer forming material is not particularly limited, and examples include a substantially square shape, a substantially rectangular shape, a substantially rhombus shape, a substantially circular shape, and a substantially oval shape. In FIG. 5, the application | coating part 61 of the peeling layer formation material of planar view substantially square shape (or substantially rhombus shape) is shown.
By providing the release layer 6 intermittently, in the skin pack package 1, the skin pack film 4 can be prevented from being inadvertently peeled off from the mount 2, while the skin pack film 4 is rolled up. The skin pack film 4 can be peeled off from the base material 5 without causing material damage to the base material 5.

Preferably, the release layer 6 has a region where the concentration of the release agent has changed from one edge of the mount 2 to the inner portion in the plane direction. Specifically, the release layer 6 is formed so that the amount of the release agent per unit area at one edge of the mount 2 (one edge of the peripheral edge of the mount 2) is higher than that of the one edge. It is larger than the amount of the release agent per unit area in the inner surface portion. Such a concentration changing region of the release agent is not limited to the case where the release agent concentration change region is provided from one edge portion of the mount 2 to the inner portion thereof, and is provided from two or more edge portions of the mount 2 to the inner portion thereof. Alternatively, it may be provided from the entire peripheral edge of the mount 2 to the inner portion.
More preferably, the amount of the release agent per unit area in the immediate vicinity of the corner of the mount 2 to be the opening start point 41 to be described later (the inner immediate vicinity of this corner is included in one edge of the mount 2) The amount of the release agent per unit area in the inner portion in the surface direction of the mount 2 is greater than the immediate inside of the corner.
By forming the release layer 6 in which the amount of the release agent at one edge of the backing sheet 2 is larger than the amount of the release agent in the inner portion, the skin pack film 4 can be applied to the skin pack package 1 with a relatively small force at the beginning of opening. (Beginning from the edge of the skin pack film 4 corresponding to one edge of the mount 2). And once the skin pack film 4 can be easily rolled up at the beginning of opening, even if the skin pack film 4 in the inner part is relatively strongly adhered to the backing sheet 2 (the inner part has a small amount of release agent, The skin pack film 4 is less likely to be peeled than the one edge part), and the skin pack film 4 can be peeled smoothly. In addition, the skin pack film 4 is prevented from being inadvertently peeled off from the mount 2 in the skin pack package 1 by making the amount of the release agent in the inner part of the mount 2 smaller than the amount of the release agent at one edge. it can.

The concentration change of the release agent may be a straight line or a curve that gradually increases as it goes from one edge to the inner part, or may be a step shape in which the concentration gradually increases from one edge to the inner part. Examples of the unit area include per square centimeter.
The amount of release agent per unit area (concentration change) is as follows: (1) The planar view shape of the application part 61 of the release layer forming material is the same and the thickness thereof is different. (2) The application part of the release layer forming material The planar shape of 61 is different and the thickness thereof is the same, and (3) the planar shape and thickness of the application portion 61 of the release layer forming material are both different.
In the example of illustration, the planar view shape of the application part 61 (high concentration application part 611) of the some peeling layer forming material in the one edge part of board | substrate 2 (the inner side of the corner | angular part of board | substrate 2 is near) is more The plurality of release layer forming material application portions 61 (small concentration application portions 612) in the surface direction inner side portion of the mount 2 are larger than the planar view shape, and moreover, the plurality of adjacent release layer formation material application portions 61 (high concentration) The interval between the application portions 611) is smaller than the interval between the application portions 61 (small concentration application portions 612) of a plurality of adjacent release layer forming materials (see FIGS. 2 and 4). Preferably, the shape of the application portion 61 (high concentration application portion 611) of the plurality of release layer forming materials on one edge is a plurality of release layer forming materials on the inner side in the surface direction of the mount 2 than the one edge. Is larger than the planar view shape of the application portion 61 (small concentration application portion 612), and the planar view shapes of the plurality of large concentration application portions 611 at one edge including the edge of the mount 2 are all the same shape, and The planar view shapes of the plurality of low-concentration application portions 612 at the inner side in the surface direction of the mount 2 than the one edge portion are the same. In FIG. 2, the high-concentration application unit 611 and the low-concentration application unit 612 are shown as filled.
The thickness of the release layer 6 is preferably in the range of 0.1 μm to 10 μm, more preferably in the range of 0.3 μm to 8 μm, and particularly preferably in the range of 0.5 μm to 5 μm. When the release layer 6 is formed intermittently (when the release layer 6 is composed of a plurality of release layer forming material application portions 61), the thickness of the release layer 6 is the thickness of one application portion 61. It corresponds to.
Since the thickness of the release layer 6 is very thin, the air permeability of the substrate 5 is not substantially inhibited.

When the release layer 6 is formed intermittently, the area ratio of the application portion 61 of the release layer forming material is, for example, 20% to 80%, preferably 20% to 60%, more preferably. 30% to 50%. The area ratio is a value calculated by the following equation 1.
Formula 1: Area ratio (%) of the application part 61 of the release layer forming material = (sum of the planar shape areas of all application parts existing within 1 square cm / 1 square cm) × 100

  Examples of the release agent include silicone resins, modified silicone resins, fluorine resins, polyolefin resins, and waxes. The release layer forming material is a resin composition containing one or more of the release agents, or a resin composition containing an acrylic resin, a urethane resin, an ester resin, or the like in these resins. Can be mentioned. According to the classification by the curing method, examples of the release layer forming material include a two-component curing type, an ionizing radiation curing type, an ultraviolet curing type, and a thermosetting type. Examples of the method for applying the release layer forming material include a gravure printing method, a flexographic printing method, a letterpress printing method, and a letterpress rotary printing method.

The adhesive layer 8 may be provided in a solid form on the surface of the release layer 6 or may be provided intermittently. As in the illustrated example, when the release layer 6 is provided intermittently, the adhesive layer 8 is preferably provided in a solid shape. In this case, the back surface of the adhesive layer 8 adheres to the surface of the release layer 6 (application portion 61) and the surface of the design print layer 7.
The adhesive layer 8 may be provided on the back surface of the skin pack film 4. When the adhesive layer 8 is provided on the back surface of the skin pack film 4, it is not necessary to provide the adhesive layer 8 on the mount 2 side. When the adhesive layer 8 is provided on the back surface of the skin pack film 4, when the skin pack film 4 is sucked when the skin pack package 1 is manufactured, the back surface of the adhesive layer 8 of the film 4 is separated from the release layer 6. It adheres to the surface of (application part 61) and the surface of the design printing layer 7.
Although the thickness of the contact bonding layer 8 is not specifically limited, For example, they are 10 micrometers-30 micrometers.
Examples of the adhesive forming the adhesive layer 8 include a heat-sensitive adhesive, a heat-sensitive adhesive, a solvent-type adhesive, an emulsion-type adhesive, a pressure-sensitive adhesive, and the like. It is preferable to use a heat-sensitive adhesive or a heat-sensitive adhesive because adhesiveness can be exhibited when necessary.
The heat-sensitive adhesive is an adhesive that is solidified at room temperature and is activated by heating to exhibit adhesiveness, and is solidified by cooling to adhere between members. The heat-sensitive adhesive is an adhesive that is solidified at room temperature and is activated by heating to exhibit adhesiveness, adheres between members, and maintains adhesiveness even after cooling.
Examples of the type of the heat-sensitive adhesive or the heat-sensitive adhesive include a delayed tack type, an emulsion type, a solvent type, and a hot melt type.

The delayed tack type heat-sensitive adhesive does not show adhesiveness at room temperature, shows adhesiveness by heating, and maintains the adhesiveness for a long time after cooling, and by printing such as gravure coating It is an adhesive that can be applied. Examples of the delayed tack type heat-sensitive adhesive include an emulsion in which a tackifier and a solid plasticizer are blended with a base resin such as an ethylene-vinyl acetate copolymer, a vinyl acetate-acrylic acid ester copolymer, and a synthetic rubber. Examples include molds.
The emulsion-type or solvent-type heat-sensitive adhesive or heat-sensitive adhesive is prepared by, for example, dissolving or dispersing a heat-adhesive resin such as ethylene-vinyl acetate copolymer and a tackifier in water or an organic solvent. The solution is an adhesive or pressure-sensitive adhesive that can be applied by printing such as gravure coating, and is used after drying after coating.
A hot-melt type heat-sensitive adhesive or heat-sensitive adhesive is an adhesive or pressure-sensitive adhesive that is melted by heating and can be applied by a hot-melt coater, an extrusion laminator, or the like. Examples of this include an ethylene resin such as an ethylene-vinyl acetate copolymer and an ethylene acrylic acid copolymer, and a base resin such as a styrene-butadiene block copolymer that is blended with an additive such as a tackifier. Can be mentioned.
As the heat-sensitive adhesive or heat-sensitive adhesive used, one having a softening point of 60 ° C to 180 ° C is usually used, and preferably a softening point of 70 ° C to 140 ° C. By using an adhesive having such a softening point, when the skin pack film 4 is heated to soften, the adhesive of the adhesive layer 8 can be activated by the heat. The softening point can be measured according to JIS K 6863.

Examples of the material for the skin pack film 4 include polyolefin resins such as polyethylene and polypropylene; polyester resins such as polyethylene terephthalate; polyamide resins such as nylon; ethylene-vinyl acetate copolymer; soft vinyl chloride; A plastic resin is mentioned. The film includes what is generally called a sheet.
The thickness of the skin pack film 4 is not specifically limited, For example, 30 micrometers-300 micrometers, Preferably, they are 60 micrometers-200 micrometers.

The skin pack film 4 is bonded to the surface of the mount 2 through an adhesive layer 8.
Specifically, the back surface of the skin pack film 4 is in close contact with the article to be packaged 3 at the part where the article to be packaged 3 is interposed. It is bonded to the mount 2 through the adhesive layer 8 at a portion where no intervening. However, due to the nature of the skin pack film 4, the skin pack film 4 is not in close contact with the entire package 3, but faces the mount 2 (although it is influenced by the shape of the package 3). It adheres substantially along the outer shape of the article to be packaged 3 excluding the part that is covered.
Note that in this specification, the close contact refers to a state of contact but not adhesion.

The bonded portion where the skin pack film 4 and the mount 2 are bonded is an annular region that is present in the periphery of the article 3 to be packaged. Specifically, as shown in FIG. 1, the adhesive portion is an end portion (right side) of a skin pack film 4 (or mount 2) extending in a vertical strip shape on each of the right side and the left side with respect to the package 3. End portion and left end portion), and end portions (upper end portion and lower end portion) of the skin pack film 4 (or mount 2) extending in the left-right direction on each of the upper and lower sides.
The non-adhesive part where the skin pack film 4 and the mount 2 are not adhered is an area excluding the adhesive part.
However, in order to form the opening start point portion 41, one or more corner portions of the skin pack film 4 and one or more corner portions of the mount 2 are not bonded. For example, as shown in the drawing, the back surface of the right corner of the skin pack film 4 facing one corner of the mount 2 is not bonded to the surface of the adhesive layer 8, and It has a slight distance from the surface or is in close contact with it. The corner portion of the skin pack film 4 that is the non-adhesive portion corresponds to the opening start point portion 41. Such an unsealing starting point portion 41 is provided with an adhesion preventing plate applied to the surface of the adhesive layer 8 corresponding to the corner portion of the skin pack film 4 when the skin pack package 1 is manufactured, and the skin pack film in that state. 4 can be formed by vacuum suction. In addition, when it is desired to efficiently exhibit the function of the opening start point 41, it is preferable to emboss the corner of the mount 2 corresponding to the start point 41. In the embossing, a pattern such as a leather pattern, wood grain, rock grain, sand grain, plain fabric, geometric pattern, or the like is processed at the corner of the mount 2.

Although the skin pack package 1 in the illustrated example is a package in which the package 3 is hermetically sealed with the skin pack film 4 and the mount 2 without any gaps, the skin pack package 1 of the present invention includes the package 3. It is not necessarily limited to the sealed and packaged form, and any object can be used as long as the article 3 can be held by the cooperation of the skin pack film 4 and the mount 2.
For example, the skin pack packaging body 1 of the present invention has a skin pack so that a part of the package 3 is exposed from one end portion of the skin pack film 4 or two opposite end portions, instead of an annular portion. The film 4 may be adhered (not shown). However, also in this case, the skin pack film 4 needs to be covered and adhered at the bonding portion so that the package 3 cannot be taken out from the exposed portion of the package 3.

The package 3 is not particularly limited, and examples thereof include various products such as cosmetics and stationery.
The shape of the article 3 is not particularly limited. Further, the package 3 may be disposed near the top, bottom, left, or right of the mount 2 in addition to the substantially central portion of the mount 2.

The skin pack package 1 of the present invention can be produced in the same manner as in the conventional production method. Briefly, the article to be packaged 3 is placed at a desired position on the surface of the mount 2 in which the design printing layer 7, the release layer 6 and the adhesive layer 8 are provided in this order on the substrate 5, and softened by heating from above. The skin pack film 4 is put on. The skin pack film 4 extends along the outer shape of the article 3 to be packaged by vacuum suction from the back side of the mount 2, and the skin pack film 4 is applied to the adhesive layer 8 activated by the heat of the skin pack film 4. The back surface of 4 adheres to the adhesive layer 8. In this way, the skin pack package 1 can be manufactured.
In addition, you may use the skin pack film 4 by which the adhesive layer 8 was provided in the back surface, without providing the adhesive layer 8 in the base material 5. FIG. The skin pack film 4 is usually softened by heating. However, when the skin pack film 4 is sufficiently soft even at room temperature, the heating can be omitted. When the skin pack film 4 is not heated, the adhesive layer 8 is heated separately.

In the skin pack package 1, a release layer 6 is provided between the design print layer 7 and the adhesive layer 8.
For this reason, the adhesive strength of the adhesive layer 8 to the release layer 6 is smaller than the adhesive strength of the adhesive layer 8 to the back surface of the skin pack film 4.
The skin pack package 1 is peeled between the release layer 6 and the adhesive layer 8 when the skin pack film 4 is rolled from one edge (for example, the opening start point 41). The peelable layer 6 itself peels off from the mount 2, or the skin pack film 4 is peeled off from the mount 2 together with the adhesive layer 8 (and the peelable layer 6). Therefore, the skin pack package 1 can peel the skin pack film 4 from the base material 5 without causing material destruction of the base material 5. And since the surface layer of the base material 5 has not adhered to the peeled skin pack film 4, the article 3 to be packaged held between the skin pack film 4 and the mount 2 can be easily taken out.
Furthermore, after the skin pack film 4 is peeled off, the design print layer 7 remains on the surface of the base material 5, so that the design displayed on the mount 2 can be seen without any trouble even after the skin pack package 1 is opened. be able to.

  The skin pack package 1 of the present invention is not limited to the first embodiment, and various design changes can be made. Hereinafter, other embodiments will be described. However, the same configurations and effects as those of the first embodiment (assuming that they have been described) may be omitted, and terms and symbols may be used.

[Second Embodiment]
In the illustrated example of the first embodiment, the release layer 6 is provided intermittently and the adhesive layer 8 is provided in a solid shape. However, as shown in FIG. The adhesive layer 8 may be provided in a solid shape and intermittently in the surface direction of the mount 2.
For the adhesive layer 8 provided intermittently, the concentration of the adhesive changed from one edge of the mount 2 to the inner side in the surface direction, similarly to the intermittently provided release layer 6 of the first embodiment. It is preferable to have a region. In other words, the intermittent adhesive layer 8 is formed so that the amount of adhesive per unit area at one edge of the mount 2 (one edge of the periphery of the mount 2) is higher than that of the one edge. The amount is preferably smaller than the amount of adhesive per unit area in the inner portion in the plane direction. By providing the adhesive layer 8 with such an adhesive concentration change, the skin pack film 4 can be started to be rolled with a relatively small force at the beginning of opening, as in the first embodiment, The skin pack film 4 can be peeled smoothly, and the skin pack film 4 can be prevented from being carelessly peeled off from the mount 2 in the skin pack package 1.
About the application part 81 of the adhesive agent in the adhesive layer 8 provided intermittently, a preferable form can be suitably adopted according to the application part 61 of the release layer forming material of the first embodiment. For example, as shown in FIG. 6, the planar view shape of a plurality of adhesive application portions 81 (small concentration application portions 812) at one edge portion of the mount 2 is the inner portion in the surface direction of the mount 2 than the one edge portion. The plurality of adhesive application portions 81 (large concentration application portion 811) in FIG.
Since the adhesive layer 8 is thicker than the design printing layer 7 and the release layer 6, the air permeability of the base material 5 is somewhat disturbed, but by providing the adhesive layer 8 intermittently as in this embodiment, It can prevent that the air permeability of the base material 5 is inhibited.
Moreover, both the peeling layer 6 and the adhesive layer 8 may be provided in a solid shape, or both the peeling layer 6 and the adhesive layer 8 may be provided intermittently.

[Third Embodiment]
In the illustrated example of the first embodiment, the design printing layer 7 formed of printing ink containing a colorant and no release agent is interposed between the base material 5 and the release layer 6. The printing layer 7 may not be provided.
In this case, although it becomes the skin pack packaging body 1 in which the design based on the design printing layer 7 does not appear on the surface side of the base material 5, it becomes possible to display a design by making the peeling layer 6 contain a colorant. .
Specifically, a desired colorant (a pigment is generally used as the colorant, but a dye may be used) is added to the release layer forming material shown in the first embodiment, and this is used. The release layer 6 that also serves as a design display may be formed on the surface of the substrate 5. The release layer 6 also serving as a design display is applied to the surface of the substrate 5 by applying a release layer forming material containing the colorant in a single layer or multiple layers by a known printing method according to the design to be represented. Can be formed.
